How do I change the image of different types of emoji on a Mac, I like the Windows emoji. Can anyone tell me if I can edit the Mac's emoji's to look like the ones on Windows.
You just have to replace the Apple Color Emoji font with another one that uses the Windows glyphs instead of Apple's. It would presumably have to use Apple's sbix format to work. I don't know if any such thing exists. You might have to use a Font Editor like FontLab to make one.
Note that emoji you send via email, etc. will always be seen using the font on the receiving machine, regardless of how they look to you.
